Chemical Structure
Description
5-Bromo-4-fluoro-2-methylbenzenethiol (C7H6BrFS) contains sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 5-Bromo-4-fluoro-2-methylbenzenethiol (CAS 873922-26-0), a certified reference material (molecular formula C7H6BrFS, MW 221.09 g/mol) for analytical method development and quality control.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
